It should be no problem. The tubes are the same size.
I still want to build a 98 SID with a carbon crown. And have a 97 Judy XC where I build in SID inners. Should just work fine and looks different.
I have to try that. I think it's possible to change the downtubes if you want to change the inner works you have to change to innertubes aswell.
I have an 97 Judy, but the innerwork is totally gone.
What should i do with it?
Sell the downtubes? They still look really good, but the inner work is all gone.
